iOS Manual Pages

iOS Manual Pages

Manual pages provide reference for a number of BSD and POSIX
functions and tools. This document is organized by manual page section.

These manual pages are a subset of the Mac OS X manual pages. This list
has been filtered by an automated process to exclude APIs that are known to
be unavailable in iOS. The list of man pages has not yet been fully
reviewed, however, so some APIs may be listed even though they are not
available in iOS.

For more information on manual pages, their organization, style,
and purpose, see the manual page for manpages.

codes, and C library routines that wrap system calls. Most of these functions
are described in headers that reside in /usr/include/sys.

This section excludes library routines that merely wrap UNIX system

routines. These functions are described in headers that reside in
/usr/include/openssl, and are split between the
